Abstract

1,214,081. Fluid oscillators. VSESOJUZNY NAUCHNO-ISSLEDOVATELSKY INSTITUT MEDITSINSKOGO PRIBOROSTROENIA. March 27, 1968 [March 27, 1967], No.14822/68. Heading G3H [Also in Divisions A5 and F1]. An artificial respiration apparatus comprises a fluid-switch element provided with a supply channel 4 communicating with the outlet of an injector 1, a first straight discharge passageway 5 adapted to communicate with the patient's lungs, a second discharge passageway 6 sloping relative to the first passageway, and a main control channel 7 which communicates with the straight discharge passageway, via a negative feedback channel (9), and is said to be characterized in that the fluidswitch element also incorporates a positive feedback channel (11) connecting the sloping discharge passageway 6 with an auxiliary control channel 8 located between the supply channel 4 and the main control channel 7. As shown, the injector 1 supplies an oxygen and air mixture through the channel 4, passageway 5, and a non-return valve 19 for inhalation by the patient or, during exhalation (through an outlet valve 20, 21, 22) the gas mixture from the injector passes into the passageway 6 and also out through an orifice 12 to atmosphere. The passageway 6 communicates via an adjustable throttle 15 with a variable volume chamber 14 (e.g. a bellows) able to expand and, with a movable wall 16, close the orifice 12. The changeover from inhalation to exhalation is caused by the rising pressure in the lungs and in the passageway 5 acting through the main control channel 7 to direct the gas mixture to the passageway 6, the positive feedback channel (11) then maintaining gas flow to this passageway. The changeover from exhalation to inhalation is caused either by the patient attempting to inspire, or, after a time period determined by the throttle 15, by the chamber 14 expanding to close the orifice 12 so that the pressure in the control chamber (13) rises. The fluid-switch 2 is said to be formed in a plate of an organic glass material.
